That's a battery pack with a real old ratshack part number.  Is it leaking?
Can you measure a voltage across it when the machine power is turned off?

Akoz,

Yeah thats most likely the back-up battery, but a bad battery would not keep your machine from turning on, unless it has damaged the reset section of the MPU board by leaking acid. When you turn the machine on look at the MPU board and watch the red LED on the MPU board. Does it just stay on or go through a series of flashes?  Also, check ALL the fuses on the rectified board, especially F3 this provides the regulated +5 volts dc for the games logic circuits. Make sure that you test the fuses out of circuit.

i dont own it yet. i am trying to see if i want to buy it.. this would be my first pin. he wants 350 Canadian. what do you think it is worth since it does not work.

Hawkypro:
Akoz,

I know that the back-up battery is not the reason why it wont turn on, the game should turn on if the battery failed, unless it leaked acid on the MPU board and ruined the reset section.  As far as value, its hard to say. hows the playfield artwork, backglass, artwork around the cabinet ect. Because it wont power up, I would not give 350 for it.
